always add f or F next to the value of variable so that compiler would understand that this is a floating literal otherwise it will take any number having point as a double by default

Answer 1

@AMIT KUMAR
I didn't have any problem in changing all occurence of 2.6 in your code to 2.6f even in code playground...

Answer 2

But then again, it's not a very good idea to use == with a floating point number in the first place :P

Answer 3

try float n=2.6f
it won't work here but definitely on other compilers like turboc++ ,dev C++ etc.

Answer 4

@Dennis I know but here I just want to explain that your number will no longer be the same while performing any other operations on that floating number, it's just a logical error which could make your program less accurate so we better use f or F next to the numbers to correct it.
